Web search for small footprint sites?

Recently discovering the "small internet" made me aware of the ridiculous page sizes that are served over http and also how much script needs to run just to render text on a blog.

My question would be, is there a search engine or other means of filtering out the huge portion of bloated sites _before_ you visit them and realize they take too long to load on a slow mobile connection or have too much script or don't even load with noscript?
